Application filed Januar a 1924.. seria1*No. e83,a59.

The principal objectsof the present invention are, first, to avoid corrosion and for that purpose to eliminatestructural steel; second, to facilitate the use of cast iron and to that end to avoid the use of special angular connections; third, to meet the requirements of various boiler'housesby the use of standard castings with slight exceptions which involve merely differences in length of the castiron hangers which form part-of the structure; and fourth, to provide anadjustable cast iron hopper structure ofwhich one end is of any standard gate size and shape and of which the other end is of variable size and shape for application in different boiler houses with merely the substitution of elements of differing and appropriate lengths. Other objects of the invention will appear from the following description and itmay be said that the invention, generally stated, comprises an ash hopper for boilers comprising a gate structure provided with cast iron hangers having at one of the ends thereof articulated connection with the gate. and having at the other of the ends thereof articulated suspension supports and a lining carried by the hangers. The invention also comprises the improvements to be presently described and finally claimedu In the following description reference will be made to the accompanying drawings forming part hereof and in which 1 Figure l'is an elevational view of an ash hopper embodying features of the invention showing )arts in section.

Fig. 2 1s a top or plan view of one-half of the same with the lining omitted, and

Fig. 3 is an elevational view, partly in sec tion, illustrating an intermediate hanger adjustable as to effective length and embodying a modification of the invention.

In the drawings 1 is agate frame, and 2 is a gate arranged to co-operate with the frame 1 and shown as mounted on rails 3.

' ers. The hangers 4 operate as buckstays and the hangers 5 are valley or corner pieces. The hangers 4 are connectedwith the gate frame by hinges 6, and the hangers or corner pieces 5 are connected with the gate frame by ball and socket or universal joints 7. The

upper ends of the hangers 4 are provided with suspension supports 8, connectedthereticulations at the ends of the hangers.

to by hinge elements 9 311C113, and the upper ends of the hangers 5 are provided with suspension supports 10 connected thereto by ball and socket or universal joints 11. 12 is a lining carried by the hangers and it may consist of a monolith or'of a number of tiles. In installing for use the suspension supports 8 and 10 are secured to a boiler-housing or structure the shape of the opening in which. determines their position and the ar-' ticulations at the ends of the hangers permit I them to assume whatever inclination may be required by reason of the constant size and shape of an appropriatestock gateframe 1 and by the particular size and'shape of the opening at the inlet of the hopper, and the lining, being of tile work, is cut to fit. Ob-

viously in some cases hangersof different lengths will be required to meet the peculiar conditions of size and shape of the inlet of the hopper "due to the construction of the 7 boiler house. Within limits the lengths or effective lengths of the hangers can be adjusted by means of the nuts and threaded stems 15, Fig. 1, or 16, Fig. 3, and in such cases all of the parts are standard. Beyond those limits it may be necessary to substitute I hangers of different lengths, but otherwise theparts, including the gate frame and-the w articulations and the suspension supports,

are selected from standard stock. The lining is cut to fit. The result of this is that the structure is peculiarly adapted to be made of cast iron which resists corrosion and that is a very important matter in ash hoppers. for boilers. It may be remarked that the pins 13 and the connections 14, '15 and 16 are separate from the rest of-the structure so that very few patterns have to be provided; The differences in angular disposition of the. hangers in respect to theparts with which they are connected are compensated for by the articulationsand adjustments when present at the ends of the hangers. In a general way the structure may be regarded as made v up of a base of fixed dimensions and a topluu of variable dimensions by reason of the ar- A change in s'ize or shape of the openings at theinlet or outlet, or requirements of height or depth, may necessitate the use of hangers or of some hangers of different lengths, but

such hangers are cheaply provided and are only necessary where the changes of length required exceed the limits of the adjustments 15 and 16.

It will be obvious to those skilled in the art to which the invention relates that modifications may be made in details of construction, arrangement and matters o'l mere form without departing from thespirit oi the invention which is not limited as to such matters or otherwise than as the prior art and the appended claims may require.

I claim: i

1. An ash hopper Structure for boilers of which the outlet at the base consists of a gate frame of standard size for ditlerent installations and which is provided with hangers hingedly connected with the frame fand provided with hingedly connected sus- 3. An ash hopper for boilers comprising a gate structure, valley corner hangers having ball' and socket connection with the gate structure, intermediate hangers hingedly connected with the gate structure, a lining carried by the hangers, and suspension supports of which some are hingedlyconnectcd to the intermediate hangers and (it which others have ball and socket connection with the valleyhangers.

4. An ash hopper structi'ire for I boilers provided with hangers, a gate structure having hinged articulation with the hangers at one of the ends thereof and constituting an outlet of fixed sizeand shape, and suspension supports having hinged articulation with the other of the ends of the hangers, whereby the inlet of the hopper may be of differentsize and shape. i i

An ash hopper and gate structure coinprising in combinationra gate frame,;cast iron hangers having hinged articulation with the frame, susupension supports having hinged articulation with the hangers, and adjusting means for changing the effective lengths of the hangers.
